T0 ALL WIOM IT'MAY CONCERN:

Be it knownthat I, SMITI .OBLENI$, of Greensburg, in the county of Westmoreland, and State of Pennsylvania, haveivented a new and useful Improvement in Car-Couplings, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, which make part of this specifica.- tionfand in which- .f Figure 1 is a. vertical longitudinal section through my improved car-coupling.

Figure 2, a'view of the book which holds the coupling-link, detached; and

Figure 3, a diagram showing the operation of the hook.

To carry out my invention construct a 'coupling-box creasing A, having a ming 0r bell-mouth B, (into which the link C is inserted when two cars are coupled together,) at its outer end, and a bolt, D, at the other, by which thc box may be secured to the end of the car. lA hook, E, of the `peculiar form shown in the drawings, has a slot, e, in its rear end. A bearingpin,f, passes through this slot and sustains the rear end of the y' hook, which arrangement allows the link to play back and forth horizontally on its bearing. A spiral spring7 g, encircies the hoek andbears against the pinf, so that the hook is always thrust forward in the box A as far. as the slot will permit it to go. A coiled spring, k, encircles the bearing-pin and serves to keep the hook down upon the bottom of the casing. The hook is provided with a handle, Z, which plays in a slot, m, in the casing, which slot serves as a guide for the hook. A-.bill-or catch, z', on the hook, receives and holds the link C. Just back of this hook the link is dared and hollowed out to form a dome-shaped recess, k, which receives, guides, and holds the link in the proper position for the book when it enters. In g. 3 the black lines show the normal position of the link, the blue lines its position whenv pushed in', and the red lines its position whenvlifted to uncouple the cars.

The operation is as follows: A coupling is placed on each end ofthe cars, as usual, and the link C inserted into one, as shown in Eg. 1. The spring h holds the coupling horizontal by holdingI down the hook. As the cars approachthe link C enters the bell-mouthB and strikes the catch z' (the outer face of which inclines backward and downward) with sufficient force to raise the hook and enter the recess lc. As soon as the link passes the catch the spring z throws it down behind the link. The end of the link now abuts against the dome c, the springg yields and prevents shocks to the coupling until the bumpers abut. As the cars separate the link r is'held by catch z', andthe cars are thus securely coupled. A cord may be connected to the handle l to lift the link to uncoupl'e the car, but it may be done by hand by a person on the platform with ease.

As by my invention theccars are coupled automatically, it is obvious that I dispense with the necessity of a person going between the cars to couple them, which necessity is the source of so many accidents.

What I claim as my invention is 1. The hook E, constructed, arranged, andoperating as described.

2. The combination, substantially is described, with the bell-mouthed casing, of the slotted yielding c0upling hook, having both a horizontal and a vertical movementin its bearing, whereby the hook acts as a, bumper, and is also made self-locking.

In testimony whereof have hereunto subscribedmy name. v
